Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:Aluminum knowledge. What is the model 3003 H24? What does H mean?
H: work hardening state.(1) Hxx state:H1 * - hot rolling, Zhang Liqiang; H2 * - continuous casting and rolling, Zhang Liqiang, part of the toughening; H3 * - after stress treatment, stable performance; H4 * - after paint or coating; H x 2 - 25% x 4 - H hardness; hardness 50% processing; H * 6 - 75% hardness; H * 8 - 90 more than the hardness.(2) Hxxx state:H111: suitable for the final annealing, but also a proper amount of work hardening, but the degree of hardening is not as good as the H11 state of the product.H112: for hot forming products, the mechanical properties of the condition are specified.H116: made for magnesium content more than 4% 5 * * * alloy products. These products have specified mechanical properties and anti stripping corrosion resistance requirements.
Q:If aluminum, with an atomic weight of 27...?
aluminum oxide is Al2O3 , or 2 part Al to 3 part O. 27 grams Al2 *2 / 54 grams Al available = 16 grams of O * 3 / X grams of O solve for X: X = 48 grams of oxygen needed next guy is right....the formula for aluminum oxide is Al2O3..sorry...I readjusted the formula above to show the change
Q:How can you turn aluminum oxide into Al?
usually, in industy, the common way used is electrolysis...aluminium oxide, Al2O3 is heated until it's molten...then cryolite is added to bauxite (aluminium oxide) to lower its melting point before electrolysis is carried out to obtain pure Al metal...
Q:on the metal activity series, aluminum sits between magnesium and zinc, and all three sit above hydrogen.?
Aluminum metal reacts with oxygen in the air to form a very tightly bonded aluminum oxide on its surface which slows the attack of acids trying to make contact with the aluminum atoms below the surface.
Q:Is there any chemical reaction between carbonated mineral water and aluminium cans?
fee, and make contact with. they are the two carbonated interior the comparable way. that is basically a sensible (no longer in my opinion) advertising ploy. A play on words suggesting that one is larger than the different!
Q:which is the right machine for aluminum welding,,,tig? , mig? or what?
It all depends on what you are doing. For light duty stuff 1/8 to 1/4 inch a spool gun will be the cheapest option. For intricate work tig. For production a push pull unit with a pulse arc but these are big $.
Q:Which statement describes a chemical property of aluminum?
The answer is statement 2 Reasons why: First, know that a chemical property of any element is something that results in the change of the chemical make-up of the element. The word for word definition in my textbook says: a chemical property is the ability of a substance to combine with or change into one or more substances through a change in the chemical formula for the substance Looking at all the other options: Statement 1: Whether or not a substance is malleable is whether or not a substance can be hammered or pressed out of shape and not break or shatter. Hammering a substance, or in this case Aluminum, does not change any chemical formula of Aluminum, it just changes the physical shape of the metal. Statement 3: If a substance is conductive of electricity, it means that the material can transport an electric current. This is not chemical because the electricity simply goes through the substance, it does not change or react with any of the atoms of a substance and change the chemical formula. Statement 4: Density is a purely physical property because it is how dense a material is, and it doesn't change the formula of a substance. Therefore, Statement 2 is the best answer because by reacting with sulfuric acid, the chemical formula of aluminum changes since the atoms recombine with the atoms of sulfuric acid and create a new substance and a new chemical formula with it.
Q:Can An Aluminum Water Bottle Go In The Fridge?
Just about anything is safe in the fridge. I put aluminum Coke cans in the fridge.
Q:How many molecules are in 1 square foot of aluminum foil?
Since aluminum foil is an amalgamation of various metals you would first need to know the full chemical breakdown in order to determine how many molecules there are in a square foot of aluminum foil. That said, if your foil was 100% aluminum, you could determine the number of AL atoms by first determining the mass of the foil and dividing by the molecular weight of AL. Multiply that by 6.022 x 10^23 to determine the number of atoms.
